Trials before Marriage

I think that persons considering marriage should have some kindof Ritual Trial by Fire,something to bring things out in peopleso that each of them knows how the other reacts and copes withadversity and also,to gauge how much each person is willing tobear in the relationship,how much responsibility,how much support can each expect from the other..perhaps a SURVIVOR type campingtrip or a very long bike ride together,like 10 days,500 miles...what do you think???.it is better for everyone involved to knowwhat they can expect from the other for better or for worse...
